Appendix D Explanation of Homing Modes


Mode 23
Circumstance 1
：
MC_Home instruction is executed while the home switch is OFF and the axis moves
in the positive direction at the first-phase speed. The motion direction changes and
the axis moves at the second-phase speed once the home switch becomes ON.
Where the axis stands is the home position when the home switch is OFF.
Circumstance 2
：
MC_Home instruction is executed while the home switch is ON and the axis moves in
the negative direction at the second-phase speed. And where the axis stands is the
home position when the home switch becomes OFF.
Circumstance 3
：
MC_Home instruction is executed while the home switch is OFF. The axis moves in
the positive direction at the first-phase speed. The motion direction changes and the
axis moves at the first-phase speed when the home switch is OFF and the positive
limit switch is ON. When the home switch is ON, the axis starts to move at the
second-phase speed. Where the axis stands is the home position when the home
switch is OFF.

Circumstance 1
：
MC_Home instruction is executed while the home switch is OFF and the axis starts to
move in the positive direction at the first-phase speed. Where the axis stands is the
home position when the home switch is ON.
Circumstance 2
：
MC_Home instruction is executed while the home switch is ON and the axis moves in
the negative direction at the second-phase speed. The motion direction changes and
the axis moves at the second-phase speed when the home switch is OFF. Where the
axis stands is the home position when the home switch is ON.
Circumstance 3
：
MC_Home instruction is executed while the home switch is OFF. The axis moves in
the positive direction at the first-phase speed. The motion direction changes and the
axis moves at the first-phase speed when the home switch is OFF and the positive
limit switch is ON. When the home switch is ON, the axis still moves at the first-phase
speed. The motion direction changes and the axis moves at the first-phase speed
